f STOV'E GRATE ANI? SUPPORT.

Application led November 23, 1923. Serial No. 676,520.

To all 'whom t may concern-.- t

Be it known that I, ALVIN G. SHERMAN, a citizen of the United States, residing at Detroit, in ythe county of Wayne and State of Michigan, have. invented certain new anduseful Improvements in Stove Grates and Supports, of which the following 'is a specication. This invention relates to stove construction and has for its object a new .arrangement of the shell construction of a. cooking stove to supportthe grates4 and do away withthe usuall grate supporting frame.

In gas `and. .vapor stoves, the construction is tending toward enameledstoves and designs` which make forv cleanliness and'sani-v tariness. A great many of the panels now used are enameled and may be easily wiped with a wet rag.- However, inthe present construction the'so-called top of the stove is usually made up of a cast iron ,frame which where it is secured to the stove shell,`

makes unsanitary joints that can not be completely cleaned and affords deep crevices for the collection of grease, soil and other lth. It .is the object of the present invention to completely do away with the grate supporting frame and so form the sheet metal walls of the shell 'construction that thesewill form suitable seats on which to rest the grates. The grates themselves are provided with suitable aprons at the'ront and sides which drop down below the plane of: the top for the purpose of iving a conventional appearance to the ont and sides of the top, and for concealing the burners and other devices underneath the grate. In the drawings:` Fig. 1 is a plan view of a gas or vapor stove employing my new grate construction. Fig. 2is a section taken on the line 2 9. of Flg. l.l

Fig. 3 is of Fig. 2.

Fig. 4 is a detail in perspective of the front grate. Fig. 5 is a vertical section through the stove showing. the warming chamber construction, taken on the line 5 5 of Fi l. Fig. 6 is a vertical section taken om a, section taken on the line 3-3 aY section taken on thee 7-7 of Fig. 5.. y l

welded together at their edges to form ay unit shell construct-ion. This unit shell construction completely eliminates all seams and joints that would otherwise form crev` ices to collect. dirty and soil. The enti-re shell unit ma)7 be enameled 0n the outside to make a clean and smooth surface which may be kept absolutely clean witha wet cloth.

In this application, my new grate and grate f supportingstructure is shown and described but `not claimed, as this grate construction can be obviously'used in a structure where,-

no welding takes place, although it is ob` viously a very valuable contribution to the sanitary stove of the character described in my companion application.

The oven wall a, or side splasher, jogs at b to forma shoulder, then continues down and forms the'inside side wall of the warming chamber, or burner pit, which wall is designated c. It continues across the bot- .tom of the warming chamber and then forms the other -side wall dof the warming chamber. It is looped over at the top lto form a grate seat c, then continues down at thel outside in the wall f to form the outside of the stove or the warming chamber. This wall construction may be a single sheet of metal bent, or conceivably, it might be several pieces seamed together, in so far ais the invention claimed 1n the present application is concerned. ,y

A second sheet of metal forms the back splasher g and the shelf h and is jogged to form a shoulder i on which the rear grate rests at the back of the stove. This unit is preferably united to the first sheet metal unit described by weldin the two edges in a butt seam, but obvious y other means of uniting could be adopted so far as the invention claimed in the present application is concerned. The two jogs in the two panely sheets, viz: those that form the shoulders b and e' and the seat e formed bythe looping over of., the Vpanel at the side of the stove formappropriate resting places for the two ates y' and k. No supl ort for the front of 'e gratas is required ausethese gra are divided along a line running from side to side of the stove top rather than front to the back as is the usual practise. However, dips are made in the shoulder b and A the seat e to take theprojections and c' l to lock the front grate from sl1d1ng-ol'.

The rear grateis provided with a side apron m, which Vdrops down a short distance at the side to provide the conventional covering at this point, that is Ordinarily furnished by the frame of the stove. The front grate lc is provided with Athe side apron n and yfront apron o .that drops down at the front and sides to conceal the parts u n'derneatli in the conventional wayi' v Now, obviously, the grates may be removed by simply 'lifting them oli; they then may be each easily cleaned. When the grates are removed, this leaves the warming chamber and back-splasher as one continuous 2 5 plication, where all the joints and crevices' an easily cleanable surface..

and completely exposed structure that may be easily wiped with a rag. Especially is this true in such a structure as I have described and claimed in my companion apare eliminated by homogeneously uniting the panels edge to edge so that all the seams and crevices are eliminated. Preferably, the panels are enameled'so as to afford able grate structure which seats by gravity on theisaid grate seats, the seats and grates having interlocking`- portions to prevent the grates sliding off. y f

2. In a cooking stove, a shell construction provided with offsets to form grate seats and continuingdown at the bottom to form the walls of the warming chamberv and arranged to form a ythird seat at the side of the stove, and a. removable grate structure resting on said seats by gravity and in`removable relation, and provided with depending4 apron portions 'at the side and front.

3. In a cooking stove, a shell forming the side-splasher and the backsplasher, and rovided with laterally oilset ortions contlnuing on to form the side an back wall of the warmin chamber or burner pit, said shellJ :formed lnto a third support atJ theI side of the stove, and a pair of grates divided on a` line running fromlside to side of the stove and resting on the two offset ortions and the third support at the side o' the stove.

4. In a cooking stove,`a sheet metal shell ,construction forming'the side-splasher and the back-splasher and oiset outwardly to form grate supporting seats, and continuing down to form the side-wall and back of` the warming chamber'or burner pit, the shell also provided with a sheet metal member that rises to the other side of the warming chamber oiburner pit and then forms a loop and turns down to form the outside wall of the stove,'said loop forming a third seat for the grates, and a grate structure removably seated on the two osets andsaid loop.

5. In a cooking stove, a sheet metal shell forming the side-splasher and the backsplashe'r and offset to form grate seats, and

continuing down to form the back and-side shell formed to provide the two sides ofv the warming chamber-or burner pit and two grate seats, and a pair of grates divided along a linerunning from side to side of the stove and bridging the 'warming chamber or `burner pit, said grates resting b v gravity on the said grate seats, and provided at th`e side and front of the stove with depending aprons. K

7. In a cooking stove, a'stove shell forming a warming chamber or burner pit in which the sheet metal forming the shell is.

formed to provide at each side ofthe warming` chamber or burner pit and the back of the warmer 'chamber or burner pit,y grate supporting seats, and a pair of grates bridging the warming chamber or burner pit from side'to side, and removably supported on said seats and provided with suitable aprons depending at the front and side.

8. In a cooking stove, i stove shell forming a warming chamber or burner pit in which the sheetmetal forming the shell is folded to form on each side of the warming chamber or the burner pit and at` the back ofthe warming chamber or burner pit, two I grate supporting seats which are an integral part ofthey sheet metal shell, and a pair of grates bridging the warming chamber or burner pit from side to side, the division .line between the said grates running from sideto side of the burner pit, the said grates being removably supported on the seats and free from support at the front of the burner shell and provided with suitable aprons depending at the front and at one side.

In testimony whereof I aiiix my signature.
